How Do PV Solar Panels Work?
Below is some helpful information about how our Domestic Solar Panels work. Our experts are ready to take your enquiries and get your Domestic Solar Panels up and running so contact us today on 0800 988 3188.
It All Starts With The Sun
Solar panels (or specifically PhotoVoltaic Solar Panels) are devices that convert light energy from the sun into electrical energy in the form of Direct Current (DC). This Direct Current, which is similar to the power you get from a battery, must then be converted into AC (Alternating Current) at a voltage (a little like electrical 'pressure') identical to our 'mains' electricity. This conversion is done by a piece of equipment called an Inverter. An invertor might be considered to be a little like having a combined water purifier and pump in a water collection system.
AC electricty coming from the inverter is then measured by a meter before passing directly into the electrical installation in your home. If you don't use it, it will go to your local community, and then by extension the national electrical grid (yes, it’s all connected).
How will you install the panels on my roof?
Normally scaffold or Mobile Elevated Work Platforms are used to gain access to the roof space. Then a lightweight aluminium frame is secured to the timbers of the roof using brackets selected according to tile type. All fixings are externally rated. The roof will continue to be completely water tight.
Finally the solar panels are secured to the frame using manufacturer specific clamps. If you have a flat roof then a wedge shaped frame is used to get the best possible pitch for the panels.
How does power get off the Roof?
The cables from the panels will normally be brought through the roof into a junction box located in the loft space. Often the inverter will be sited in the loft space too. Finally a single mains cable will be routed by the neatest possible route to the existing consumer unit (Fuse board) in the house.
Will it work if its cloudy?
Solar PV operates on light, rather than heat, so even if the day seems cool – if there is light, the system will be generating electricity. PV systems will generate electricity all year round although for a number of reasons the output will fluctuate seasonally, with the most electricity being produced in the bright summer months.
Will they work on my home?
Well as we are in the Northern Hemisphere, a south facing roof will receive the most sunlight – For the best results from a Solar Generator the roof would be orientated somewhere between South West and South East, with a 30 degree slope and of course no tree’s, chimneys or other buildings to cast a shadow over them.
BUT If you don’t have a south facing roof space don’t worry, east-west splits are also very common and this type of installation will still produce about 85% of the energy that an equivalent sized array on a south facing roof would.
How much money will I save/earn?
Over the course of a year, a solar photovoltaic system will save you money by reducing your electricity bill, and you will get paid every kWh you generate, regardless of whether you use it yourself or export it to other users. For more information see the section on investment potential.
How do I receive payments for the electricity I generate?
A phone call to your electricity supply company will lead them to send you a form to fill in. We will help you complete it.
How long will the system take to pay back the energy used in its manufacture
How long does a PV cell have to generate electricity for until it pays back the carbon (energy) required to make it? This is generally expected to be less than 4 years. After that it is making a real and positive contribution to the environment of our planet.
